Kenosha County investigators and a national animal rights group said they discovered close to 70 animal carcasses buried on the property of David and Paula White.

The couple faces a host of animal neglect charges.

Police said even more animal remains could be buried there, but the department didn't have the manpower to sift through the acres of land.

"We found a number of other horses buried under the carcasses that were on the surface, they were only buried about a foot deep, still with recent decomposition," Deputy Chief David Morgensen said.

Morgensen said the Whites have lived at the property on 128th Street for more than 20 years. For a while, they operated a horse riding farm.

Investigators said they're concerned about how long rotting carcasses have been buried so close to a stream that feed the area's well system, potentially contaminating drinking water for many families nearby.

"We could be talking E.coli and other germs we don't want in there, and there are laws for that," Morgensen said.

Erica Smith lives across the street from the Whites.

"I have small children, so the idea that I could be giving them water that has something in it that could be bad for them is really scary for me," Smith said.

Police said dead animals weren't just buried outside -- there were carcasses found inside the house, as well.

"They had some animals in the freezer that were absolutely forbidden from being possessed," Morgensen said.

Morgensen said to expect more charges. He said the case is only about 25 percent complete.
